The making of Knight Without Armour (1937) was one of Donat’s most dramatic, publicity-heavy misfires. Donat had been wavering over projects and Korda had committed to Knight Without Armour in large part because of Donat’s indecision; when Marlene Dietrich — a European starlet under a huge $450,000 contract — arrived in Britain to co-star, the atmosphere around the shoot intensified into a far larger furore than anyone expected. Within days of filming Donat suffered a nervous collapse and was admitted to a nursing home. The interruption was so severe that production came to a complete stop for around two months amid fevered talk of replacing Donat.
The flashpoint exposed the fault lines between star egos, studio money, and on-set morale: Dietrich reportedly threatened to walk the picture if Donat were replaced, and Korda ultimately waited for Donat’s return rather than recasting. The episode left scars — it cemented Donat’s reputation as a brilliant but fragile leading man whose health and temperament could derail a major production, and it underscored the uneasy bargaining that occurred whenever high-value stars (and their multimillion-dollar contracts) collided on set. The halt also contributed to the narrative that Donat, despite towering talent, would be a limited film presence because of the instability surrounding him.
